If an object weights 40 N on the Earth, it would weigh only 10 N when its distance from the center of the earth

doubles,
halves,
triples or
quadruples???

How do I figure this?

Ever heard of an inverse squarelaw? Gravity is one of them,

For the weight (and the acceleration of gravity) to fall to 1/4 of the value at the surface, the distance from the center of the Earth must double.
